Hot mixtures of sanding dust and paint/var-
nish residuals or other chemical materials in
the filter bag or the vac filter can self-ignite
under unfavourable conditions, such as spark-
ing from sanding metal, continuous sunlight
or high ambient temperatures. To prevent
this:
–
Avoid overheating the material being
sanded and the power tool.
–
Empty the dust collector/container rou-
tinely.
–
Observe the material manufacturer’s
working instructions.
–
Observe the relevant regulations for the
materials being worked.
Emission values for sound
(Two-figure – specifications as per ISO 4871)
Extension cable.
If the use of an extension cord
is required, its length and con-
ductor cross-section must be adequate for the
application in order to prevent a voltage drop
in the extension cord, power loss and over-
heating of the power tool.
Otherwise, the
extension cable and power tool are prone to
electrical danger, and the working efficiency is
decreased.
Recommended dimensions of extension cords
at an operating voltage of 120 V – single-
phase a. c., with only KBB 30 connected:
Intended use of the power tool:
Magnetic base drill for drilling with annular
cutting tools on ferrous materials in con-
trolled environments using the cutting tools
and accessories recommended by the manu-
facturer.
